In this study, the fracture structure of three coals (Sulu K-1, Acihk K-2 and Cay Dogu Ayak) from two different seams in the Zonguldak Basin located on the Black Sea coast of Turkey have been analyzed in relation to coalbed methane recovery. X-ray computerized tomography (CT), light microscopy image analysis and scanning electron microscopy (SEM) analysis have been performed on mine coal samples to have a better understanding of distribution of minerals, fracture morphology and apertures and matrix/fracture interactions via examination of fracture surfaces.
